Renne Bank in about 60 m depth of water (Fig. 25). During the first three
days stormy northeast winds prevailed, followed by east winds that sub-
sided after February 27. Between March 1 and 4 light winds from various
directions prevailed.
During the period of the northeast storms and the east storms
it was possible to fish only with lihes. The captures per unit effeort
were more than 20 salmon per 1000 hooks and thus rather favourable, but
they dropped with the diminishing winds to fewer than ten salmon per 1000
hooks. The favourable winds allowed to employ driftnets beginning on March
1, 1962. The Catches amounted to 130, 40, 5, and 2 salmon per 100 nets
between March 1 and 4 and. yielded on March 1 a total of almost 1500 fish
(Table 25).
It cannot be established with certainty whether the large num-
bers of salMon were present on the fishing grounds prior to March 1, when
lines were still used for fishing. It must, however, be assumed that in
that case the catches with lines would have been much greater. It is thus
very probable that the fishing on March 1 encountered a very numerous

group of salmon that happened to pass through at that time. The -e-etp-tttre-e

per unit effort show that on the second day only stragglers were still
being caught. On March 1, the catch amounted to 30 salmon per 1 km 2 of
fished area, on March 4 it was only 0.45 salmon.
Let us attempt to draw a conclusion from the known facts in
regard to the behaviour of the salmon.
The fishermen had taken up their driftlines on the afternoon
of February 28. These had been set out around 0400 h in the morning and
had yielded on an average 6.9 salmon per 1000 hooks. In the afternoon the
wind had dropped so much that already at sundown of the saine day it became
